NATO does acting on the basis of constant control aviamissiyu Baltic (Baltic Air Policing Mission, BAPM). BAPM is less than link 4 NATO fighter jets stationed at the Lithuanian Air Force Base and created to patrol the Russian border for 4 months. A similar procedure was started in 2004, when the Baltic States (Lithuania, Latvia and Estonia) have joined the bloc NATO. Baltic countries wanted some presence on its territory of old times members of NATO, if only to show the Russian that something has changed. Many Russians consider the Baltic States "lost provinces." Since the 18th century Baltic States were part of the Russian Empire. They are are independent after the First World War (1914-18), but was again occupied by the USSR in 1940. And only in 1991 with the collapse of the Soviet Baltic states returned their independence, and they are determined to keep it.
In 2008, the U.S. Air Force sent four F-15 aircraft on alert BAPM to patrol along the border with Russia. These things have not gone unnoticed in Russia, which hitherto tormented that she was on the losing side in a cool war. Link F-15 was the second South American link in BAPM, and was the first to link the F-16.
The introduction of the countryside each other Member States NATO for training or operational work is mundane. In the end, the mutual defense of NATO is a shared responsibility of its members. In addition, countries Baltic States not yet have their fighters. So Makar, BAPM provides a nominal air defense, while the Baltic countries will not be able to do this without the help of others. And it will happen by the end of the decade.
